Вот такая новость за 2015 год насчёт зарядок:
The Calgary Airport Authority unveiled a unique new passenger amenity today at Calgary International Airport (YYC), a WeWatt electronics charging station, with the help of Her Royal Highness Princess Astrid of the Belgians, Representative of His Majesty the King.
This three-seated stationary bike, developed in Belgium, allows users to charge up their devices by generating power through pedaling, and the installation at YYC is the first in a Canadian airport.
